Abstract
The utility model relates to a centering device. The centering device comprises a rubber wing and a sleeve, wherein the rubber wing is installed in the sleeve, three wing panels which are evenly distributed in the circumferential direction are arranged on the outer surface of the rubber wing, installation grooves are formed in positions, corresponding to the wing panels, of the sleeve, the wing panels are arranged in the installation grooves, a chamfer is arranged at the left end of the rubber wing, a fixing sleeve is arranged at the left end of the sleeve, a locking sleeve is arranged at the right end of the sleeve, and a sliding check ring is arranged between the sleeve and the locking sleeve. The centering device has the advantages that requirements for machining precision of dies and parts are not high, and the manufacturability is good; the centering device is adaptable to instruments with different outer diameters; the rubber wing can be replaced rapidly after being damaged by scouring; the structure is compact, and space is saved; the rubber wing which is made of rubber purely is good in vibration damping performance and reliable in work.
Description
Technical field
The utility model relates to a kind of centralizer.
Background technology
Centralizer is the vitals that guarantees instrument location, radial vibration-reducing is provided.Underground working is very severe, and centralizer not only will bear erosion, high pressure and vibration, is also likely operated in hot environment.Existing centralizer is a kind of is to consist of matrix, glue wing sleeve, and axial dimension is large, and need to guarantee that electric, the signal of instrument connect, complex structure.Another kind is the sleeve centralizer of sheet with rib sleeve molded rubber, can be sleeved on instrument cover face, has saved axial space, but mould complex and expensive, the required precision of sheet with rib sleeve is high, is difficult to processing.
Utility model content
The purpose of this utility model is to provide a kind of centralizer, to overcome prior art above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of centralizer, comprise the glue wing and sleeve, the described glue wing is arranged in described sleeve, and described glue wing external surface is provided with three fins that are uniformly distributed circumferentially, position corresponding with described fin on described sleeve is equipped with mounting groove, and described fin is placed in described mounting groove; Described glue wing left end is provided with chamfering; Described sleeve left end is provided with fixed cover, and described sleeve right-hand member is provided with lock sleeve.
Further, between described sleeve and described lock sleeve, be provided with slip back-up ring.
The beneficial effects of the utility model are: less demanding to mould, part processing precision, and good manufacturability; The instrument that can adapt to various outer diameter; Fast changeable after the erosion of the glue wing damages; Compact conformation, saves space; Full rubber glue wing vibration damping is good, reliable operation.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of centralizer described in the utility model embodiment;
Fig. 2 is the front view of sleeve described in the utility model embodiment;
Fig. 3 is the lateral view of sleeve described in the utility model embodiment;
Fig. 4 is the front view of the glue wing described in the utility model embodiment;
Fig. 5 is the lateral view of the glue wing described in the utility model embodiment.
In figure:
1, the glue wing; 2, sleeve; 3, fixed cover; 4, slip back-up ring; 5, lock sleeve; 6, chamfering; 7, fin; 8, mounting groove.
The specific embodiment
As Figure 1-5, a kind of centralizer described in the utility model embodiment, comprise the glue wing 1 and sleeve 2, the described glue wing 1 is arranged in described sleeve 2, the described glue wing 1 external surface is provided with three fins that are uniformly distributed circumferentially 7, position corresponding with described fin 7 on described sleeve 2 is equipped with mounting groove 8, and described fin 7 is placed in described mounting groove 8; The described glue wing 1 left end is provided with chamfering 6; Described sleeve 2 left ends are provided with fixed cover 3, and described sleeve 2 right-hand members are provided with lock sleeve 5.Between described sleeve 2 and described lock sleeve 5, be provided with slip back-up ring 4.
In actual production, the described glue wing 1 is full rubber pattern casting die, selects high temperature resistant tear-proof rubber to make; Described sleeve 2, fixed cover 3, lock sleeve 5 select high-intensity non-magnetic alloy to make; Described slip back-up ring 4 selects the thermostability engineering plastic that friction factor is low to make.
During application, the described glue wing 1 is sleeved on instrument cover face together with described sleeve 2.Described fixed cover 3 is sleeved on instrument one end, and is threaded with described sleeve 2; Described slip back-up ring 4, lock sleeve 5 are sleeved on the instrument other end, and described lock sleeve 5 is threaded with described sleeve 2.Described lock sleeve 5 is being threaded in rundown process with described sleeve 2, promotes the described glue wing 1 of described slip back-up ring 4 extruding, makes the described glue wing 1 distortion produce the enclasping force to instrument, and described centralizer is fixed on instrument.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection domain of the present utility model.
